User Summary Backyard Baseball 2004 is another in the Backyard Baseball series in which children can create and manage their own baseball team while challenging computer-made teams of various skill levels. Backyard Baseball 2004 follows the other Backyard Baseball games in style and gameplay, including MLB players in their cartoony child form and allowing a host of powerups and trick plays that compliment the game type. This year's installment is unique in that it was only published for the GameCube console.
